BT40 25mm Hydraulic Chuck x 83mm Gage Length, TSC
Part # 04-0920BT40-HC-25-83MM
Description
This BT40 hydraulic milling chuck has a 25mm bore diameter and a 83mm gage length. The chuck accepts precision straight-shank collets (optional) to reduce the bore and hold smaller diameter tools. The hydraulic fluid within the chuck compresses to provide equal pressure around the cutting tool shank, providing high grip strength, low runout, and excellent damping properties. It is through-tool coolant (TSC) capable, with a M16x2.0 pull stud/retention knob thread.Download documents
